Personal Portfolio Webpage Challenge-Feedback Needed

Hi this is SooMitt. I’m fairly new (noob) on Free Code Camp, its been less than a month since i joined. I made a decent Portfolio with minimum needed for “user story”.

Here is the link :

It functions the way I want it to on full screen, but when you resize the browser (or view on mobile phones). The Bootsrap carousel slide and it’s headings seems to disappear under the toggled navbar. I need guidance to correct that issue.

I also made a contact message form using Bootstrap, however its just a placeholder for now. I need guidance on how to make it functional. Can it be done just using CodePen?

I’ve also attached fullscreen and resized screenshots.

Thanks everyone, Your feedback would be appreciated.
